Shapes

[graceful crow]

ooo

I like this question

[hybrid brook]

so r u gonna help me

[graceful crow]

Yes

lemme work it out

So

do you want the answer or do you want to understand it @hybrid brook

[hybrid brook]

i have the answer but i don’t know how to get to it

so i want to understand it

[graceful crow]

cool

so

let the width of the rectangle = x

So the length of the rectangle will be 3x+4

[hybrid brook]

shall i draw a rectangle

go slowly pls brw

[graceful crow]

Do you get how I got here

the length of the rectangle is equal to the width of the rectangle multiplied by 3 and add 4 so 3(x) +4

[hybrid brook]

my brain hurts man lemme think

[graceful crow]

Cool process this and then give me the green light

you get it?

[hybrid brook]

yeah i get it

[graceful crow]

cool now

let’s decipher the question

now what I would do is rewrite the question in a way that I could understand

The area of the square is 66 more than the area of the rectangle

[hybrid brook]

there’s two shapes ?

[graceful crow]

so the area of the square is = to the length of the square ^2 + 66

[graceful crow]

Yes

we have one shape which is 3x+4 by 3x+4

you may want to draw both shapes

[hybrid brook]

like this

there’s two squares ? or one rectangle and one square

[graceful crow]

One rectangle and one square

Ignore the top

Those are our two shapes

[hybrid brook]

oops i drew it wrong

[graceful crow]

tell me when you want me to continue

In the meantime I want you to recall the area of a square and the area of a rectangle

[graceful crow]

It’s like this

[hybrid brook]

oops ok i’ll re do it

oh wait i realise my mistake

[graceful crow]

read the question, the length of each of the sides of square is equal to the length of the rectangle

[graceful crow]

you do?

I will continue explaining, just in case.

Now, the area of the square is (3x+4)^2 -66

That’s because we want to make the two areas of the shapes equal so we can solve for x.

[hybrid brook]

ok so (3x+4)2 is the the area of the sq

2 as in squared

[graceful crow]

that, then subtract 66

[hybrid brook]

y

[graceful crow]

to answer the question, we need the area of both shapes to be the same. As area of square is 66cm greater than area of rectangle , we need to subtract 66 from the area of the square to balance it out.

[hybrid brook]

i got an ugly quadratic man

[graceful crow]

Let’s see

[graceful crow]

Right, but that’s not yet finished

[hybrid brook]

ohhh

i know what to do

[graceful crow]

now equal that quadratic to the area of the rectangle

[hybrid brook]

i divided by 9

😨 oh

ok i’ll make it equal

[graceful crow]

Then rearrange and you should get a quadratic

[hybrid brook]

this is so long

[graceful crow]

now factorise

[hybrid brook]

it’s non calc

[graceful crow]

the roots are there

have faith in yourself

you can factorise

[hybrid brook]

how can i factorise a coefficient without a calculator 💀

i’ll try

[graceful crow]

have you not done it in class?

do the coefficient * c

[hybrid brook]

i have but it’s so long

[graceful crow]

just try it

you should get a nice simple number

think of factors of -75 that add to 10

[hybrid brook]

what two numbers multiply to make -75 and add to make 10

yeah i was gonna ask

i can’t think

15 and 5

[graceful crow]

yup

[hybrid brook]

but i gotta switch up the signs

15 and -5

[graceful crow]

yes and remember you have that coefficient to resolve

[hybrid brook]

ik

[graceful crow]

cool

[hybrid brook]

alr i got x

x = 5/3

[graceful crow]

what’s x = to

[hybrid brook]

or x=-5 but i’ll use the pos

[graceful crow]

yes now that’s the width of the rectangle, but the question also asks for the length too

[graceful crow]

Yes because a length can only be positive

[hybrid brook]

ik

[graceful crow]

So look back for the equation for the length, and plug your value in

[hybrid brook]

yay i got an answer

that’s not my answer btw

it’s just my working out

[graceful crow]

so what’s the length?

[hybrid brook]

9cm

is that right

[graceful crow]

also do you understand each of the steps and why we did them

[graceful crow]

yup!

[hybrid brook]

yee i do actually surprisingly

i’m so silly that i didn’t even draw it at first

it was a Q in my mock

and i skipped it 😭

[graceful crow]

yea the question was simple quadratics the difficult part was just creating the equation

[graceful crow]

it’s fine, you’ll still do good- it’s not the end of the world. Furthermore, now you know so at least it’s a learning process. NEVER SKIP A QUESTION, UNLESS TOU HAVE NO TIME! you never know you might be able to get method marks

[hybrid brook]

this question would’ve taken me 15 minutes

haha

[hybrid brook]

i did get an 8 overall

thankfully

[graceful crow]

examiners look to award marks, marks aren’t deducted

[graceful crow]

That’s still very very good

[graceful crow]

I doubt that, and tbf if you had a lot of time- I would still do so

[hybrid brook]

i did understand tbf and caught on quick

i just need to focus

[graceful crow]

like In my case I finish 90% of the paper in 40 minutes and use the rest of my time on the last few really challenging questions

[graceful crow]

yea

[hybrid brook]

40 minutes 😭

[graceful crow]

time management is crucial

you’ve shown to yourself that you can do the maths, you just need to decipher the question

[hybrid brook]

decipher ?

[graceful crow]

understand

decode

[hybrid brook]

ahh

ok soz my vocabulary is primary skl lvl

[graceful crow]

That’s why I like to write the question in simple terms

[graceful crow]

Tbf my vocabulary isn’t the best either

[graceful crow]

And break it into steps

[hybrid brook]

okb but this question is hard hard

but at the same time east

easy

[graceful crow]

One hard question can be very daunting, 5 easy questions are manageable

so make your one hard question into 5 easy parts

[hybrid brook]

yeah i will tysm tho i’ll try my hardest to ‘decipher ‘ questions 😭😭

nice word

[graceful crow]

haha, no problem

Rather get it wrong now than in the real thing

[hybrid brook]

nahhh if IK i got a 6 marker wrong i’d not be able to sleep following results day

[graceful crow]

True

but if you want to ask me

I don’t think this question was worth 6 marks

I think that’s a bit too high

maybe something like 4

[hybrid brook]

🥲

4 is mad

5 i think

[graceful crow]

tbf you want it to be less, so if you do get it wrong you lose less marks

[hybrid brook]

oh right that’s very true 😭😭 i got 52 in this paper and i could’ve got 58 damn

[graceful crow]

genuinely should be 4

1 for making both length equations
1 for squaring and rearranging
1 for factorising
1 for final method mark, eg finding the length and width

[hybrid brook]

there’s gonna be a 6 marker in our gcses that shakes everyone up watch

[graceful crow]

stop, let’s not scare ourselves

it’ll probably be some horrific exam anyways

[hybrid brook]

💀 nah i can feel it in my bones some mad questions

[graceful crow]

Both are very strong scores

[hybrid brook]

i’ll be tearing up on the exam seat

[hybrid brook]

i did better on calc papers

[graceful crow]

Esp with them saying that the grade boundaries are going to be tough

[hybrid brook]

nc is my enemy

[graceful crow]

What did you get

[hybrid brook]

overall 184

[graceful crow]

mashallah

That’s very good

[hybrid brook]

out of 240

ye

[graceful crow]

have you finished your mocks

[hybrid brook]

yeah

[graceful crow]

same

[hybrid brook]

mock 2 are in march

[graceful crow]

I’m so glad they are gone

[graceful crow]

Same

I think I did very very well in maths

[hybrid brook]

6 weeks untill my next mocks i can’t even relax

what’d u get

[graceful crow]

accounts for the fact that I probably failed biology

[graceful crow]

217

[hybrid brook]

😨

217

that’s so high

good job

[graceful crow]

yea I got 72 in paper 1 77 in paper 2 68 in paper 3

[hybrid brook]

how u getting 77

damn

[graceful crow]

paper 3 I dropped careless marks

Probably could’ve gotten 225

[graceful crow]

The exam was very very nice

it’s almost as if they made the exam for me

grade boundaries were kinda low for paper 2 as there were a few complex geometry questions

[hybrid brook]

ohh what was the hardest topic

[graceful crow]

on paper 2

Lemme show you the question that has everyone perplexed

[hybrid brook]

ok i can do it in a second watch

💀

[graceful crow]

mashallah

we will see

zoom in

[hybrid brook]

how many marks ?

[hybrid brook]

can’t lie i hate shapes

[graceful crow]

5

[hybrid brook]

5 marks

calm

[graceful crow]

I think it was too much work for 5 marks

[hybrid brook]

really .. no hope for me

SECTORS included

[graceful crow]

seeing as a simple vector question was also 5 marks

[hybrid brook]

one sec lemme try this

vectors are sickly

[graceful crow]

Try it, I recommend you read the question carefully

[graceful crow]

Do you wanna see the question

[hybrid brook]

no

i hate it man

don’t bother it’s a topic i need to re touch

[graceful crow]

I finished the exam in like an hour and 10 minutes and just watched everyone sweat over the question

[graceful crow]

well I recommend you do so

[hybrid brook]

i get so bored of it

we were learning it for 3 weeks

[graceful crow]

my teacher told me I was the only person in the year who got full marks 💀💀💀💀

[hybrid brook]

i was sick and tired

IN WHAT

[graceful crow]

of the question I showed you

I got 5 marks

[hybrid brook]

oooohh

lemme work it give me a sec

[graceful crow]

I could never my teacher lit taught the whole topic in two days

[graceful crow]

worst part about this was after the exam everyone was telling me I was wrong.

[hybrid brook]

no i’m in a bad set so we went from BASIC to q’s with 3 marks and 2 marks and then finally 5 marks

[graceful crow]

go work it out and get back to@me

[hybrid brook]

and then proving it

[graceful crow]

I really wouldnt mind that but tbf for you to be in a bad set and still get an 8

props to you

that’s an amazing job

[hybrid brook]

my class is dumb

acc that’s mean

they’re getting U’s i should be moved up right

[graceful crow]

yea

they should move you up to set 2 if not set 1

set 1 100% but no less than set 2

[hybrid brook]

i am in set 2

[graceful crow]

set two is not a bad set

[hybrid brook]

but set 2 is full of foundation students who just moved up

[graceful crow]

wtf

[hybrid brook]

and they are slow so my teacher spends ages on it

[graceful crow]

In my school set 1 and 2 is acc some prestige set

[hybrid brook]

atleast i do FM

[graceful crow]

mashallah

FM on top

FM > regular maths

[hybrid brook]

set 1 ppl act like they’re the best i dislike most of them

[graceful crow]

🥸

I am definitely not part of set 1

I am 100% telling the truth

tbf there is some crazy range in my set

[hybrid brook]

what relation has the sector with the cone

i’m doing the q btw

[graceful crow]

the base of the cone, is the sector

[hybrid brook]

oo

this seems okay

[graceful crow]

you can do it

It’s just recognising one thing that’s difficult

[hybrid brook]

do i work out AOB major or minor

[hybrid brook]

welp looks like i’m not getting it

[graceful crow]

it’s all in the question

[hybrid brook]

is the cone a full circle

like the base

[graceful crow]

the base of the cone is a circle.

a complete circle

[hybrid brook]

so the base of the cone is the sector with a piece cut out of it

or a full circle

[graceful crow]

basically the base of the cone is the sector, joined together

Use the diagrams they’ve given you to understand

[graceful crow]

OAB of Sector OACB

[hybrid brook]

i know how to do this yay

lemme@work it out

[graceful crow]

tell me when you get a number!

[hybrid brook]

is this calc question

[graceful crow]

Yes

[hybrid brook]

so i need the use the curved surface area formula in this Q

do**

[graceful crow]

you can use that

there’s two ways of looking at it

it’s also given just in case you don’t know it

but the way I solved it didn’t use the curved surface area formula

do it in the way you are comfortable in.

[hybrid brook]

do i join a line between A and B on the sector to make it a triangle

just tell me if that’s part of the method

no hints

[graceful crow]

no

[hybrid brook]

alr

[graceful crow]

Don’t overthink it

If you want a hint hmu

[hybrid brook]

im stuck 😭😭

ok give me a hint

[graceful crow]

The curved area of the cone is the area of the sector ( method 1), or the circumference of the cone is the arc length of the sector ( method 2)

[hybrid brook]

rlly

r u just supposed to know

[graceful crow]

The diagram is the clue

[hybrid brook]

omg

didn’t even notice

[graceful crow]

always look at the diagram

Now use that

[hybrid brook]

got an answer

i did something silly to get this

wait no

my answer was wrong

lemme redo

GOT IT

264 degrees rounded to 3sd

sf**

[graceful crow]

mashallah

That’s right

[hybrid brook]

ITS RIGHT

omgg

it took me ages tho

😭😭

[graceful crow]

that’s fine

[hybrid brook]

had to work out slanted height

[graceful crow]

you are doing better than loads of my set then!

[hybrid brook]

😭😭 thankss

[graceful crow]

I was the only one in my set who got the answer

So barring me, you are better than my whole set

Feel proud of yourself

[hybrid brook]

hahha

i do , it was alot of work tho

i feel smart

[graceful crow]

wishing you the best in your GCSE maths journey

[graceful crow]

yea that’s why I don’t think it really was worth 5 marks

too much work

too many steps

[graceful crow]

you should

[hybrid brook]

u too

ok i need to sleep but ty for helping me 👍
